WATER-FILTER.

i Specification of Letters Patent.

Application filed. May 22, 1909. Serial N o. 497,582.

To all 'whom it may concern:

Be it known that we, IsAAc K. Hlsnv and RANDOLPH M. WARDLE, citizens of the United States, residing at Carlton, in the county of Yamhill and State of Oregon, have invented certain new and useful Improvements in Water-Filters, of which the following is a Vspecificatiomreference being had therein to the accompanyingdrawing.

This invention relates to filters orstra'innection with feed pipes of boilers, pumps Src., and the principal object ofthe same is to provide a filter or strainer which can be cheaply constructed, andreadily connected with a supply pipe'so as, toA thoroughly separate the foreign particles from the liquids passing through the same.

It will be understood, of course, that the Aessentialfeatur'es of the invention involved in carrying out the objects of the invention generally stated above are necessarily susceptible of changes in details and structural arrangements, one practical and preferred embodiment of the same being shown in the accompanying drawings, wherein- Figure 1 1s a central longitudinal sectional view of the improved filter or strainer.

Fig. 2 is a horizontal sectional view taken on the line 2-2, Fig. 1. Fig. 3 is a perspective view of the strainer. Figs. 4 and 5 are similar views of the plates between which the straining screen is retained.

Referring to said drawings by numerals, it will be observed that the improved strainer or lter comprises primarily a cylindrical vessel 1 having its ends threaded on its exterior. The vessel l is preferably used in a vertical position its upper endbeing closed by means of a flanged cap 2 having a threaded engagement with the threads thereon, and the lower end is similarly closed by means of a bottom cap 3. Both of t said caps are preferably provided with a nut-shaped exterior 4, as is shown in Fig. 2. The bottom cap 3 is provided with a pendent tubular extension 5 threaded exteriorly for engagement with a drain cock or the like 6.

The vessell on one side, and preferably engagement with a pipe (not shown) for conveying the filtered water from said vessel. The tubularV extension 8 is preferably arranged 'in a lower vertical planev than the extension 7.

The inner surface of the vessel 1 is provided with longitudinally.arranged, oppositely disposed grooves 9 and v10, respectively, said grooves extending from end to :end of said vessel. ers for water supply pipes equally adapted 2 for household purposes or for use-in con-` Thel strainer for theimproved vfilter is kcomposed of two rectangular plates 11 and 12 which are of the same length as the vessel 1 and of a width to permit of a snug, but sliding lit within the oppositely disposed grooves 9 and 10. Each plate is provided with a central, elongated slotor opening 13. The plate 11 is equipped with a guard strip 14 which is substantially. the same width `and length as its slot and is retained in as to act upon any material passing through lthe slots therein. Saidl screen is of the same shape andsize of said plates.

. In practical use, the screen is placed between the plates, and the plates and screen are forced into the vessel l, being guided by means of the grooves 9 and'l() which receive the edges of said plates and interposed screen. The plates are arranged so that the guard stri 14 will project across the inlet extension so as to deflect the incomin liquid and cause it to fall to the bottom o the vessel until it overflows through the screen vand into the opposite side of the vessel and thence out through the discharge extension 8. By this means the sediment is deposited upon the bottom of the vessel and may be readily drained out through the tubular extension 5 of the cap 3.

It will be seen from the foregoing that all parts of the filter may be separated to permit a thorough cleaning of the same, and when in an assembled condition, the filter is tightly sealed eXcept through its inlet and discharge and the drain extension.

It will be understood, of course, that the nut shaped exterior of the caps is for the Patented Nov. 9, 1909.'

purpose of permitting the tightening or loosening of the same by means of a wrench. l/Vhat we claim as our invention is l. A device of the character described comprising a vessel provided with an inlet and plates, and a deflecting strip having an angular end connection with one of said plates and arrangedV parallel with the slot therein and also in the path of the incoming liquid.

3. A device of the character described coinprising a vessel provided with an inlet and a discharge, said vessel being provided with oppositely disposed side grooves, a pair of slotted plates slidably fitting said grooves, a screen interposed between said plates, and a guard strip carried by one of said strips and arranged in the path of movement of the incoming liquid.

4:. A device of the character described comprising a vessel, sealing caps for each end thereof, plates slidably mounted in said vessel and provided with a central elongated slot, a screen between said plates and covering the slots therein, and a guard carried by one of said plates and arranged parallel with but spaced from the slot therein.

5. A device of the character described comprising a vessel provided with an inlet and a discharge, sealing caps for each end thereof, a pair of plates slidably litting said vessel and each provided with a complementally arranged centrally located slot, a screen between said plates and covering the said slots, and a guard strip carried by one oi said plates and arranged parallel with but spaced from the slot therein and also in the path oit p the incoming liquid.

V6. A device of the character described co1nprising a vessel provided with an inlet and a discharge, a screening device therein, a guard strip carried by said screening device and held in the path of the incoming liquid, detachable end caps for said vessel, and a drain pipe extension projecting from one ot said caps.

7. A device of the character described comprising a vessel provided with oppositely disposed laterally projecting inlet and discharge extensions, detachable end caps for said vessel, a drain pipe extension projecting from one of said caps, a filtering screen in said vessel, and a delectory strip in said vessel and arranged in the path ot' the incoming liquid.

In testimony whereof we hereunto aiix our signatures in presence of two witnesses.
